1 Claim.

This invention relates to a broadcast seeding attachment for a tractor of any type, and has for the primary object the provision of a device of this character which may be easily adapted to a tractor and driven from one of the drive or traction wheels thereof to assure seeding of a given area of ground with a determined amount of seeds regardless of the tractor being operated in high, intermediate or low gear and which permits seeding, harrowing and covering operations to be successfully carried out during one operation by the tractor.

With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a fragmentary top plan view showing my invention adapted to a tractor.

Figure 2 is a fragmentary side elevation illustrating the same.

Figure 3 is a fragmentary side elevation illustrating a combined clutch mechanism and drive for the seeder to one of the tractor wheels.

Figure 4 is a sectional view taken on the line 4-4 of Figure 3.

Figure 5 is a fragmentary view partly in section showing a control lever and its different positions.

Figure 6 is a plan view showing a coupler employed between a pair of seeders.

Figure 7 is a fragmentary edge View showing the 35 same.

Referring in detail to the drawings, the numeral I indicates a fragmentary portion of a conventional type of tractor wherein one of the drive or traction Wheels is shown at 2, with a fender 3 40 overlying said wheel. Arranged at the rear and extending transversely of the tractor I is a supporting beam 3 connected to the platform 4 of the tractor I by braces 5. 'I'he beam 3 supports one or more seeders 6 of a conventional construction 45 wherein the operating or power translating shaft is connected to a sprocket chain 1 by a sprocket gear 8. As shown in Figures 6 and '7, a coupler 9 may be employed for connecting the operating shafts I0 of a pair of seeders so that one operating 50 shaft of one seeder may turn the operating shaft of the other seeder, the coupler consisting of a plate II connected to the operating shafts by clamps I2.

Extending forwardly of the bar 3 and suitably connected thereto is a supporting bar I3 having journaled thereto a shaft I4 equipped with a sprocket gear I5 over which the sprocket chain 'I is trained. The supporting bar I3 supports the shaft I4 in alignment with the hub of thewheel 2. The forward end of the bar I3 is supported by a brace I6 which is connected to the fender 3. A brace Il is arranged between the bar I3 and the bar 3.

A frame I8 is suitably secured to certain spokes of the wheel 2 so that said frame will be disposed adjacent to the hub. The frame I8 rotates with the wheel 2 and has secured thereto aplate I9 forming a journal for one end of the shaft I4. The plate I9 has formed thereon oppositely arranged drive lugs 20, either of which may engage a drive dog 2|, the latter being pivoted to a plate 22 keyed to the shaft I4, as shown at 23. One end of the dog is connected to a coil spring 24 acting to position the end 25 of the dog in the path of movement of the lugs 20. An extension 26 is formed on the dog and is arranged out of the path of movement of the drive lugs and may be engaged and disengaged by a catch member 2l, the latter being of a resilient construction and secured to the bar 3 and brace II. Normally, the catch member 2l disengages itself from the extension 26 so that the end 25 of the dog will be in the path of movement of either of the drive lugs 20 by the action of the spring 24 so as to establish a drive between the shaft I4 and the hub` of the wheel.

A control lever 28 is journaled on the shaft I4 and is capable of occupying either of the positions shown in Figure 5 and has secured thereto an ear 29 riding against the catch member 21 so that when said lever is positioned, as shown in dotted lines in Figure 5, the catch member 27 will be forced downwardly to engage with the extension 26 and rock the dog 2| on itspivot, moving the end thereof out of the path of either of the drive lugs, thereby interrupting the driving connection between the hub of the wheel and the shaft I4. The control Vlever when positioned as shown in full' lines in Figure 5 permits the catch member 2'I vto rise and become disengaged from the extension 26 and thereby free the dog so that its end 25 may move into the path of movement of either of the drive lugs by the action of the spring 24 and thereby'when engaged by either lug will establish the drive between the hub of the wheel and the shaft I4.

A tractor equipped with a seeder or seeders as described and driven by one of the traction wheels will permit a determined amount of seeds to be planted to a given area, regardless of the opera- Y torlV of the *tractor in'either `Alovv, interxnediate f -or'hgh gear. Also the seederror seeders 'adapted Vto a tractor permits Vthe latterto pull theusual Y harrow and drag so that theseeding, harrowing Y and covering operations-may be successfully accomplished VinV one operation vrby the'tractor.
